look up chris chow on youtube with his GN and a TT SBC. I think he is the fastest stock suspension GN or was. his was 1100HP at one point. My friend has an 87 GN and an 89 TTA. Both are modded but with different blocks so he doesn't window the original. Both cars have around 45K miles on them. He still takes them to the track regularly.

It's your car, make it fast and fun. Who cares what engine you put in it as long as you drive the thing.

A setup like mine will make a ton of power without breaking the bank (relatively speaking):

347" Aluminum block
Stock crank
Callies Compstar Rods
Wiseco Forged/Coated 2618 Boost pistons (-25cc)
Stage III heads (58cc chambers)
CheaTR cam (117 LSA, smooth idle, low overlap for turbo)
TC76 Turbo

Should make 700+ RWHP and get 25+ MPG with near-stock drivability.

Something else to consider would be swapping in a modern 3.8L

The LSx + turbo + intercooler is going to make for a crowded engine bay and place a lot of weight in front of the wheels. The downside to the 3800 Series II is that you wouldn't be able to run your 200-r4 and would have to replace it with a built 60 degree 4L60e transmission.

What's torque again? I see folks say that once in a while.

You can make 600-700rwhp with a 6.0 LQ4 iron block setup no problem. Add a cam, head studs, and the rest of the stuff and you'll get there.

I had a GT47-88 348 8:1 setup in my Formula, went 10.0@139mph @ 16 psi might have gone 141 with some experimentation. Kit later went 8.8@150 in another car not sure of the boost.

I like the torque. It makes the car fun to drive around without having to wind the engine out in order to get something out of it.

FWIW, I sold my GN to fund my Metro. I think you'll be money ahead to do that. If you do go with a V8, try not to chop up too much so you can go back to stock at some point (or the next owner can). Then you haven't destroyed any long term value.

And they did not make tons of 86 GN's less than 6000, there were over 22000 of the 87's, same car except for the grill.

A boosted LSx makes PLENTY of torque.

loki993

There were only about 30 or 40k TOTAL GNs. Not a shitload by any stretch.




Yes that is a sweet car, its actually a WE4 not a GN, which is coincidentally even more rare than GN.


Yeah I would imagine the car would be kinda rough for 6500. Even a "cheap" GN in decent shape should be able to pull 8k. got any pics??

klrv6

And only 752 made like mine with t-tops in 86. The frame boxing is the only real permanent thing that will be done to it. A good number of frame off restorations over at turbobuick.com do this for safety and strength.


Yea, for 6500 it wasn't too bad, I just hate to put a ton of money in an old V6 when the same money will get me something I can find in a junkyard and take a beating.

Adam Connell

Do it. I threaten to do mine all the time.

When and if I ever do my GN, I will be running a nice little twin setup.

Not sure if I will keep the 200r or go with a 4l80.

Eiter way, it's on the back burner. My engine isnt original, and it would cost considerably more to make a GN clone.

Just make it a nice clean build and no one should ever give you an issue.

I dissagree, The LC2 109 is Junk, I have seen so many split in half, Caps cracking , heads lifting etc.

Big deal it wont be origanal , who cares you only live once, Buld it KLRV6 they way you want to, you have a good vision of how its going to come out. It will be very reliable and sound great NA , blower or turbo, nothing like a V8 sound.

After you install that LSX powerplant you should show up on GM's door step and show them this is how they should have built it.
Thant what i am going to do, and if a New style GN was to be built today , what would to power it with ??????

I have a complete LS2 out of a 06 vette , only 2,000 miles on it , i am installing my own custom grind methanol injection blower camshaft with a set of lunati double/duel valve springs, hardend push rods and a set of rebuilt stock set of harlem sharp stock rocker arms.

Thats it to the LS2, O yeah i cant forget My Procharger system, I will set the pullys for 8-10 PSI and spray a custom twin nozzle Methanol injection system , set up by me, run VP M-5 fuel.

A 4L70 tranny with small converter , i guess around 3,200-3,600 stall.

I have to figure out what headers/exhaust to run, i want SS 3' exhaust with some type of X pipe and 1.75 long tube headers, I am thinking on dynomax ultra flow mufflers, i dont want the car to loud, and have the exhaust exit behind the rear tires just like a Stock T type.

I picked up a SUPER clean white with black out 87 T type a few months ago, I am going to install the motor over the winter, with new Rewired wiring harness GNX dash gauge cluster, Fuel pressure gauge mounted on hood. LSX badges. That all the money i have will take me, tranny, exhaust, dyno tune next spring

X2. The LC2 is a turd. It was the Fuel Injection, Intercooler and Turbo that made that car notable, not the 25 year old V-6 design. V-8 sound is one of the finest things on the planet. It is almost primal.

I'd recommend that you go for it. You have a good foundation already. If you aren't happy with the way the LS engine runs, then you can always go back to the LC2. I've had 5 Turbo Buicks. My current one is my favorite of all of them. It's a turbo LQ4 powered 87 Regal Limited. Here's my thread.

Hi Kevin87turbot,, my Turbo T looks just like yours, but i got diffetent seats, mine look the exact same as GN seats except all solid silver grey

I got to post up some pictures

I yanked that LC2 like a bad tooth for a LS2, LOL

You know if you go on any of the turbo buick sights and talk like this , they will cry like babies and boot you off. last winter when i bought the LS2 and C6 Procharger head unit system, i asked a few ? about what was involved to install a LSX PowerPlant. Man they got pissy and all insulted, They are a true V6 Turbo Family , but so are we

X50. This is the only place I am not a red-headed stepchild for my swap.
BuickV8.com and TurboBuick.com are both excellent communities, but they are nothing short of disgusted with me when I talk LSX. So, I just don't talk motor stuff on those forums.

I built a couple GN powered RX-7's and then went LS1. Never looked back. 500hp on 91 octane n/a with streetable mods with a stock LS1 shortblock.

Most the gaskets on an LSx motor are reuseable, the cylinder head design is awesome, stock intakes flow well, you can use stock manifolds to build up a turbo setup, good oiling and ignition systems, the stock block and cranks can handle 1000rwhp+.

My built LC2 was $$$s to build (forged rods/JE pistons, RJC girdle etc), overpriced stock cast cranks, with fully ported iron heads I think they barely flowed 210cfm. Just about any ported or aftermarket LSx heads will flow 300cfm+. I sold that engine before I even ran it and glad I did. Money pits. Actually 2 brand new GN crankshafts for something like $450 each after dumping all my parts collection.

When you can make 600rwhp with a $500 5.3 engine, $700 MPT70 turbo, $200 injectors, $100 used Z06 cam, and $75 yellow Z06 valvesprings and a tune reliably you know you are onto something good. Go with the LSx setup and never look back.

LC2 in its day and in the late 90's was a bad *** setup. But it was developed from a 70's engine where they weren't trying to make 500rwhp+. Technology has given birth to the GenIII/IV/V small block and its kicking ***.

Yes Turbo buick guys have to stop living in the 80's

I say just do it. I used to have a 72 Skylark with a big block Buick engine and I took it to Buick nationals etc so I have been around the Buick guys and that mentality. My buddy has 3 Gn's and would NEVER consider putting a V8 in any of them. I would do the conversion for the V8 sound if for no other reason, but like others have already said once you go LS you will never go back.

As far as the collector value goes, just do whatever you want. I was going to hack up a Typhoon when I found my Blazer. I was arranging to fly to Texas and pick up a mint Ty I had located when I found my Blazer on a local used car lot. The Blazer was less than half the price of the Ty but it isn't a Ty and thats what I wanted. I have spent lots of $$ on things like a Ty console and floor shifter, transfer case etc etc and its still just an old Blazer. Since you already have the GN you should just go for it !!

As far as selling it and getting a regular regal and clone it and dropping a motor....**** that

Don't listen to these guys, cars come and go. They are just cars. Pull that old v6 outta there and have some fun.

When the funds get right a GN with an Iron lsx block with twin turbos will hit the streets. For the ones that dont like it... & can kiss my ***.
